Deposit measurement apparatus, deposit measurement method, and computer-readable storage medium storing deposit measurement program

摘要

An object is to improve the precision of estimating a blockage ratio or a deposited-scale thickness. In a deposit measurement apparatus (60) that estimates a blockage ratio of a gap between a wall surface of a through-hole and an outer surface of a heat-conducting pipe or the thickness of a deposit deposited at the gap, an eddy-current flaw detection probe (61) acquires an eddy-current flaw detection signal by scanning inside the heat-conducting pipe with a sensor; and a processing device (62) estimates the blockage ratio at the gap or the thickness of the deposit deposited at the gap by using the eddy-current flaw detection signal for the gap of the pipe-supporting-plate protrusion in the through-hole.
